I have a Sony MEX 5DI head unit I recieved sometime ago and have a slight problem. I hooked up all the wires to the best of my knowledge (bought it off Ebay some time ago with no instructions) and It works fine but retains no memory when the vehicle is turn off. The wires are color-coded like so:

Yellow = Vehicles 12v power for radio

Red= Constant 12v (memory?)

Black= Ground

Med Blue=Remote

Dk Blue= Power Antenna

Orange= Dimmer

Lt Blue= I have no idea.

Am I hooking up something wrong? My friends Sony deck does the same thing and has similar wires, it's a complete pain we have not experienced when installing other brands actually. Any help would be appreciated.

Exactly, you have your memory and switched/acc/turn on backwards.
